Apparent viscosity and dynamic angle contact were measured to evaluate the influence of tannin content on rheological behaviour and the wettability process. A classic shear-thinning behaviour was observed for all adhesives. Apparent viscosity and equilibrium contact angle reached a maximum value for low CT content. This effect was attributed to the existence of associative interactions between CT and SPC. Bonding quality parameters (wood failure percentage and shear strength) of the glued-wood joints were measured according to EN 302-1:2004 standard. 1 % CT w/w on SPC adhesive showed the best performance for dry conditions. These adhesives were suitable for glued-wood joints for indoor environments.</p> Leandro Esposito Emiliano Manuel Ciannamea Ignacio Solaberrieta Juan Carlos Piter Roxana Alejandra Ruseckaite Pablo Marcelo Stefani Copyright (c) 2022 Leandro Esposito, Emiliano M.

From clothing to protective equipment, fabric analysis mostly focused on its physical properties. Still, its flammability has not been well studied, such as ease of ignition, heat release, and toxicity. This paper reports the flammability properties of fabric in military applications. The ignition time, heat release, and smoke production of six commercially available military fabrics are discussed in this article. The fabrics analysed are cotton, polyester-cotton, coated nylon, and kenaf fabric. The fabric grouping into the coated and printed fabric while cotton and kenaf were tested as a comparison. Results indicated that coated fabric (N420D and N1000D) showed higher TTI compared to printed fabric (P35C65, P35C65M, and P65C35). It is affected by heat flux, the areal density of the sample, sample mass, and the number of sample layers. Coated fabrics (N420D and N1000D) indicate higher EHC compared with other fabrics. For printed fabric, a relatively lower EHC was observed as it indicates incomplete combustion. Total heat release of the samples tested was presented as an integration of the HRR vs time curve. Coated samples show the highest values for PHRR and THR values compared to printed and cotton fabrics.</p> R. Yahaya N. Zahari W.A.W. Wan Adnan Copyright (c) 2022 R. Yahaya, N. Zahari, W.A.W.

Technologies with greater operation time are needed to be modified or replaced as per the requirement of the current scenario. In small and medium enterprises of developing countries, almost all the reporting activities are conducted in Microsoft Excel. The manual operation in Microsoft Excel takes a long time (17.37 minutes, only if there was one order of only one article with one color) of the users; furthermore, there can also be a greater chance of error in the report. In the same way, the order costing report at the ABC footwear company of Lahore is prepared manually in Microsoft Excel which used to take a long time to be prepared along with the greater probability of errors in the report. Because of the above-mentioned reasons, the order costing report was decided to be automated with the help of visual basic for applications (VBA) in Microsoft Excel. The manual procedure including all the activities was collected from the planning and costing department of ABC Company. Moreover, all the activities were listed down and their time study was conducted. VBA macros were programmed with the objectives of automating all the manual tasks of the order costing report in Microsoft Excel and eliminating the chance of error (calculation error made by the employee). Macros, were programmed by the use of conditional statements, (i.e. if and else conditions) and various types of loops, (i.e. Do while loop and for loop). Automated decisions were made with the help of conditional statements during the operation and the conditional statements were circulated with the help of loops across the whole worksheet. Two userforms were designed for the execution of macros by the click of command buttons (having macros at their back). Total eight worksheets were incorporated into the automated template. All the programmed VBA macros were explained with the help of flowcharts made in the Microsoft Visio. After the report was automated, a time study of operations performed after each click was conducted with the help of stop watch. The data obtained by the time study was entered into Microsoft Excel so that the time of old and suggested methods could be compared. Comparison of both methods indicated that the suggested method took 85.92% less time as compared to the old method of preparing the order costing report. At the same time, the report made by the suggested method was free of errors and the workload of employees was also reduced.</p> Muhammad Ahmed Kalwar Muhammad Faisal Shahzad Muzamil Hussain Wadho Muhammad Ali Khan Shakeel Ahmed Shaikh Copyright (c) 2022 Ahmed Kalwar 2022-01-31 2022-01-31 3 1 29 59 10.4995/jarte.2022.16390 Reactive dye adsorption desorption and stamping by halloysite http://ojs.upv.es/index.php/JARTE/article/view/16583 <p>The scientific community is continuously developing new methods for the recovery and purification of water, since the precious resources of our planet are increasingly scarce and we must work to save and clean our waters. One of the methods used is the use of adsorbent and absorbent materials that remove from the water those substances that are harmful to the environment are nanoclays. In this work, the effect of a nanoclay, specifically Halloysite, to adsorb reactive dyes has been used as an example of a technique. As an example of this type of coloring substances, Reactive Yellow 2 has been used, which has been subjected to the adsorbent action of the mineral, having an adsorption of 78% in the proposed experiment. Subsequently, it has undergone a desorption process by applying temperature to the dye-clay hybrid, so that later, thanks to the effect of solvents (HCL and / or NaOH), the desorption process in aqueous solution can be completed, obtaining a recovery from the dye. up to 17.67% adsorbed, which is interpreted as a very good result. At the same time, the ability to stamp the HNT has been tested once the dye has been adsorbed and used on a PES / CO textile, demonstrating the viability of this process and evaluating its results by rubbing and washing fastness tests.</p> Daniel López-Rodríguez Barbara Micó-Vicent Eva Bou-Belda Pablo Díaz-García Copyright (c) 2022 Daniel López Rodríguez 2022-01-31 2022-01-31 3 1 61 66 10.4995/jarte.2022.16583 Development of linear programming model for optimization of product mix and maximization of profit: case of leather industry http://ojs.upv.es/index.php/JARTE/article/view/16391 <p class="JARTEAbstract">When the decisions are analytically supported they cannot be challenged and at the same time, the quality of decision increases. This paper is about proposing such a model which provides the analytical support to the decision for the selection of footwear articles to be produced. This paper aimed to suggest the analytically supported decision-making for deciding the number of pairs of different articles to be produced in a way that the cost and profit could be minimized and maximized respectively. This research was conducted at the ABC leather footwear company of Lahore Pakistan. The data was collected from the costing executive of the planning and costing department. Costing and profit analysis of the collected data was conducted in Microsoft Excel as per the company`s traditional method of calculations. The linear programming (LP) model was then formulated and implemented in Microsoft Excel by using solver add-in. Outputs of both the traditional method and LP model were compared. The comparison revealed that with 22% less production, 39% more profit could be earned if the selection of articles and their production quantity would be calculated accordingly. This model can be modified and used in fast-moving consumer goods (FMCGs) industries for making product mix strategies. A major limitation of the present developed model is that it is based on the scenario of the footwear industry so it cannot be used as general for other applications.</p> Muhammad Ahmed Kalwar Muhammad Ali Khan Muhammad Faisal Shahzad Muzamil Hussain Wadho Hussain Bux Marri Copyright (c) 2022 Muhammad Ali Khan 2022-01-31 2022-01-31 3 1 67 78 10.4995/jarte.2022.16391
